Orion hit the shacks.
The K2 falls apart at 1 kHz interfering signal spacings, and I
doubt the IC-7800's 6 kHz roofing filter will be much better.

Orion's 1 kHz IMD performance increases to 91 dB with Preamp On.
Hopefully Elecraft will address better filters if they decide to
make a K2+.
Enjoy those contests that have signals only every 5 kHz! ;-)
